PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 634,415, dated October 3, 1899.

Application'filed February 6,1899. Serial No. 704,646. (No model.)

To all whom it may concern:

Be it known that I, FRANK KNoBELooH, a citizen of the United States, and a resident of Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in Paper Boxes, of which the following is a full, clear, and exact description.

My invention relates to an improvement in what is termed a collapsible paper box, which can be readily and quickly made to assume box form, and is more especially intended for what is known as a pail-filler for use in packing candies and the like, as will be more fully hereinafter described; and it consists in certain modifications and improvements on the box shown and described in my Patent No. 606,671, of July 5, 1898.

In the drawings, Figure 1 is a perspective view of my improved box folded into shape. Fig. 2 is a plan view of a blank or sheet of cardboard cut and scored to form my box, with the portions to form the bottoms also cut and scored. Fig. 3 is a plan view of a blank cut and scored in still another manner. Fig. 4 is a plan view of a blank cut and scored in a modified manner and the side flaps on the extension forming one of the bottoms omitted.

Like letters of reference indicate identical parts in all the'figures.

A blank of cardboard or other suitable material is cut the desired shape and scored where the same is to be folded, the dotted lines indicating scores and the heavy lines the cuts. The portions a, b, c, and (1 form the four sides of the box, and efone of the bottoms, preferably the outside bottom, and the extensions g 7L form the other or inside or false bottom.

The box is formed in the following manner: The portions or sides a and dare brought together, which is possible by reason of the scores shown in dotted lines, and the flap a is glued to the side or portion d, either on the inside or outside, as desired, and as seen in Fig. 1. One of the bottomswe will say the outer bottomis formed by an extension either of the side wall a or (Z, as shown, scored diagonally, thus forming the portions 6 f, and is provided with a flap f,'which is glued to the wall or side (I or a, as the case may be, depend- 'ing,of course,upon which portion of the blank the extension forming portions (2 fis attached to, thereby secu ring the bottomin place. The inside or false bottom is also formed of one portion of the blank by an extension of the sidesl) c. This portion is scored in the diagonal manner shown, thus forming the sections or extensions g h. The extensions 9 It may be folded along the score either inwardly or outwardly when the box is collapsed, and the the same is true of the extension 6 f, and either.

may be used for the outeror inner bottom. I have shown the extensions g h, Fig. 2, provided with side flaps g h, which, however, may be omitted, if desired, as shown in Fig. at. These flaps when the blank is in box shape and the inside bottom in position are bent into a perpendicular position and lie against the side walls a d and tend to brace the false bottom and hold the side walls outward and prevent their collapsing. After bringing the sides together and the flaps are glued in place the blank will then be in complete box form, as shown in Fig. 1. The flap h being glued to the lower edge of the side wall 0 will readily permit the bottom g 7L to be folded inwardly along the diagonal score, so as to lie fiat when the box is collapsed. This flap it" may be formed integral with-the side wall 0, if desired, and then attached to the portion h.

In Fig. 3 I have shown a slightly-different manner of cutting and scoring the blank, in

which the portion forming the inside bottom is an extension of the side 0 instead of b. In this case the portion g is provided with a flap g", corresponding with the flap 7t in Fig. 2, and which is glued to the side wall Z), or, if desired, this flap g" may be made integral with the side wall Z) instead of the bottom portion. In Fig. 3 I have shown a flap d integral with the side (I, which in Fig. 1 is shown integral with the side a.

It will of course be understood that the portions 6 may be extensions of the side 01 instead of a, as has been shown in the figures, or a portion may be made of an extension of each, as may also be the case with'the extensions g h, which have herein been shown as integral with one of the intermediate sides only, my invention consisting in the production of a box of trapeziform and having double bottoms formed of extensions of either two or three or all four sides of the box, and I do not limit myself to the particular construction shown in the drawings.

Of course it will be understood that the details of construction may be varied for reasons which may exist in particular cases-for the purpose of economy of material, for example. I desire, however, to produce a box with two bottoms extending substantially over the entire base, and not half-bottoms. At the same time it will be understood that the words substantially over the entire base do not necessarily mean absolutely commensurate with the base, but substantially so, and even if one of the bottoms or both of the bottoms for the purpose of economy of material or for any otherpurpose are made slightly smaller it does not alter the substantial results and effect.

In Fig. 4 I have shown a blank with the bracing flaps or extensions g 71 omitted, as they are not essential.

lVhat I claim is- 1. A paper vessel made of a single blank of suitable material, cut and scored to fold into trapeziform, with double bottoms, extending substantially over the entire space or base, one bottom consisting of an extension of one of the ends, the other bottom consisting of an extension of one of the intermediate or narrower sides, each of said extensions scored to form two practically triangular divisions for folding, and marginal flaps arranged to overlap the sides and bottoms where they are glued, substantiallyas and for the purpose described.

2. A paper vessel made of a single blank of suitable material, cut and scored to fold into trapeziform, with double bottoms, extending substantially over the entire space or base, one bot-tom consisting of an extension of one of the ends, the other bottom consisting of an extension of one of the intermediate or narrower sides, each of said extensions scored diagonally to form two practically triangular divisions for folding to permit collapsing, substantially as and for the purpose described.

8. A paper vessel made of a single blank of suitable material, out and scored to fold into trapeziform, with double bottoms, extending substantially over the entire space or base, one bottom consisting of an extension of one of the ends of the blank, the other bottom consisting of an extension of one of the in termediate or narrower sides, each of said extensions scored diagonally to form two practically triangular divisions for folding to permit collapsing, the extension to form the inner bottom provided with marginal flaps to fold perpendicularly to brace and hold the box firmly in shape when pushed to its normal position, substantially as and for the purpose described.

4. A paper vessel made of a single blank of suitable material, cut and scored to fold into trapeziform, with double bottoms, extending substantially over the entire space or base, said bottom consisting of two extensions, one extension attached to one of the end or broad sides, and the other attached to one of the intermediate or narrower sides; the extension on the end or broad side arranged to be glued to the other broad side, and the extension of the intermediate or narrower side, arranged to be glued to the adjacent narrower side, each of said extensions scored to form two practically triangular divisions for folding, substantially as and for the purpose de scribed.

5. A paper vessel made of a single blank of suit-able material, having four sides and donble bottoms, extending substantially over the entire space or base, said bottoms consisting of extensions of two of the sides, each of the extensions cut and scored to form two practically triangular divisions to permit the blank to be folded into trapeziform, substantially as and for the purpose described.
